This retrospective study was conducted at Hamad General Hospital, Qatar, to describe the demographic data, clinical features underlying diseases, antimicrobial susceptibility, and outcome of A. baumannii infection. It involved all adult patients 15 years of age or older who were managed at Hamad General Hospital for A. baumannii infection from January 1, 2012, to December 31, 2013. We identified a total of 239 patients with A. baumannii infection, of which 182 (76.2%) were males. The mean age was years. The majority of the episodes (25.1%) occurred in elderly patients (≥65 years) and the most commonly identified site of A. baumannii infection was the respiratory tract, 117 (48.9%). Most episodes of infection, 231 (96.7%), were hospital-acquired and high rate of nosocomial infections occurred in the medical intensive care unit, 66 (28.6%). All patients had underlying medical conditions. Maximum resistance was seen to cefotaxime, 147 (58.3%), and minimum resistance was seen to colistin, 2 (1.4%). Of the 239 isolates, 102 (42.7%) were susceptible and 137 (57.3%) were multidrug-resistant. The in-hospital mortality in our study was 31%. Male gender, multidrug resistance, and septic shock were found to be independent mortality predictors.
